Yes, it is still a crime. Even if the girl did give consent to have some sort of sexual relationships with that man. It is not considered rape, but it is considered statutory rape. Please read the following information, and if this was something that happened recently to you or someone else please contact local authorities!

Statutory rape is illegal sexual activity between two people when it would otherwise be legal if not for their age

In accordance with the FBI definition, statutory rape is characterized as non-forcible sexual intercourse with a person who is younger than the statutory age of consent. The actual ages for these laws vary greatly from state-to-state, as do the punishments for offenders.

Many states do not use the actual term "statutory rape," simply calling it rape or unlawful sexual penetration among a variety of other titles. These laws rarely apply only to intercourse, but rather to any type of sexual contact.
